drivers/spi: Add controller protection type
Some SPI controllers support both READ and WRITE protection add a variable to the protect API for the callers to specify the kind of protection they want (Read/Write/Both). Also, update the callers and protect API implementation. BUG=None BRANCH=None TEST=test that the mrc cache is protected as expected on soraka. Also tried if the read protection is applied correctly.
